|
What is the structure and Function of cell membrane ? |
Structure: Phospholips bilayer with proteins semi- permeable Function: Control what move in and out of the cell
|
|
|
What is the weakness of cell membrane |
It can be destroy by anything that destroy a protein and fat |
|
|
What happen in Animal and plant cell in Hypotonic ? |
Hypotonic ( higher water concentration) Animal: The cell burst , lysed Plant: The cell wall become trugid |
|
|
What happen in Animal and Plant cell in Isotonic ? |
Isotonic ( Event concentration) Animal and Plant : Normal |
|
|
What happen in Ani and Plant in Hypertonic ? |
Hypertonic ( Lesser water ) Animal: The cytoplasm in animal shriveled water move out of the cell Plant : cytosome move inward , the cell shrived Plasmolyzed |
|
|
what is osomosis ?
|
Net movement of WATER from an area of higher water concen to an area of lower water concen through semi-permeable membrane
|
|
|
What happen if out body lack of Vitamin B12 Vit C, Vit D, Vit E, Vit K? |
B12- nervous system disorder Vit C- Delayed wound healing Vit D- kidney damage Vit E- possible anemia Vit K- Anermoa , liver damage |
|
|
What is so important for organic compound ? |
For normal metabolic function act as a coenzyme required for certain enzymatic reaction to take place
|
|
|
What is Diffusion ? |
Net movement of molecules from an area of higher concen to lower concen Passive transport( No energy required) for gases and minerals
|
|
|
What is Facilitated Diffusion ? |
Same as Diffusion help to transport glucose + oxygen have 2 ways channel and carrier faster than normal |
|
|
Active transport ? |
Lower to higher concen required in form of ATP and special protein |
|
|
Which molecule does diffusion and facilitated diffusion help to transport ? |
Diffusion: gases , mineral Facilitated diff: Glucose and oxygen |
|
|
why facilitated diffusion better than normal diffusion ?
|
Facilitated diffusion allow molecule to move faster than the normal diffusion. |
|
|
Name organic compound ? |
Hydrogen , Oxygen and Nitrogen |
|
|
What is monomers and polymers ? |
Monomers is small similar molecule join together to make large polymers. Polymers consist of many monomers join together .
|
|
|
What is Monosaccharides ? the function and example |
Basic building blocks of all the more complex carbohydrates F: main source of energy in living things, Primary source Ex: Glucose and Fructose
|
|
|
Disaccharides , Function and example ? |
Two mono that are bounded together F: Pri source of energy Ex: Sucrose , Maltose
|
|
|
Polysccharides , Fucntion and example ? |
complex large group of mono energy storage molecule provide support structure in cell walls ex: starch in plant Glycogen in animal
|
|
|
What is the function of protein ? |
Provide the cell most of structure and chemical activity . For example haemoglobin , muscle and enzyme. |
